Title: Improvements in Mechanism for Winding Yarns and the like on Bobbins after Discharge from Twisting Mechanism.
Inventor: WHITE MARK BILLINGTON
IPC: B65H54/14
Filed: 1918-05-17
Abstract: 121,902. White, M. B. May 17, 1918. Spindle apparatus; building-motions; driving- arrangements.-In a device for winding yarn on to bobbins in which the yarn is taken direct from the twisting head and wound in conical layers upon a bobbin, the yarn-guiding mechanism is arranged to move longitudinally of the bobbin, and the direction of travel is controlled through contact of the mechanism with the yarn wound on the bobbin. The bobbin 7, Fig. 3, is mounted on a spindle 77 in a rotating frame comprising end plates 64, 65 and tie-rods 72. The yarn is passed through the hollow hub 66, and through a hole 76 in the plate 64 to a guide-plate 94 which lays it in conical layers upon the bobbin. The guide-plate 94, Figs. 4 and 5, is pivoted to a member 90 pivoted to and straddling across a frame 88 sliding on the upper pair of tie-rods 72. A spring 99 holds the yarn-guide 94 in contact with the yarn on the bobbin. The member 90 is adjusted about its pivot 89 by a nut 93 on a screw 91 working against a spring 92. The frame 88 carries a spindle 102 with a cranked end connected by a spring 103 to the pivot 89. This spindle has mounted on it arms 100, 101 adapted to engage the screws 74, 75. The guide 94 has at one side lugs 104, 105 embracing the cranked end of the spindle 102, so that, as the guide rises or falls over the coned surface of the yarn on the bobbin. one or other of the lugs moves the spindle 102 far enough to allow the spring 103 to pull it over the dead centre and put one screw out of action and bring the other one into action. The bobbin is mounted on a spindle 77 pivoted to an extension 81 adapted to slide through the trunnion 67 of the rotating frame against the action of the spring 82. The other end of the spindle engages in a ferrule 79 in the end plate 64. The spindle is driven frictionally through the engagement of a loose pulley 84 with a shoulder on the extension 81. The friction is adjusted by a spring 109. The screws 74, 75 are driven bv gears 107 rotating around a stationary gear 108. The frame is rotated by a pulley 68.

Title: A method of producing l-glutamic acid by fermentation
IPC: C12P13/14
Filed: 1957-03-14
Abstract: l-Glutamic acid is produced by culturing Micrococcus glutamicus No. 534 (ATCC 13032), or one of its l-glutamic acid-producing mutants (as defined below) in a medium containing ammonium ions, fermentable sources of carbon and nitrogen, and inorganic materials under aerobic conditions, while maintaining the pH at 6-9 by the addition of acid-neutralizing agents.  The ammonium ions may be furnished by the presence of urea in the medium.  The micro-organisms must (i) be capable of producing a -keto glutaric acid from saccharidic material; and (ii) have a strong l-glutamic acid dehydrogenase activity, particularly towards the reductive amination of a -ketoglutaric acid. Suitable carbon sources are fermentable carbohydrates, such as glucose, fructose, sucrose, maltose, xylose and/or hydrolysed starch. Suitable nitrogen sources are urea, ammonia, ammonium salts, peptone, corn steep liquor, hydrolysed casein, digested fish meal, meat extract and/or digested soya bean meal.  The acid-neutralizing agents may include urea, ammonia or caustic alkali.  A suitable temperature for the fermentation is 27-30 DEG  C., and the preferred pH is 7.0-8.5.  The general characteristics of Micrococcus glutamicus No. 534 are given.  Specification 811,688 is referred to.

Title: Improvements in or relating to the laying of moored mines from submarines
IPC: F41F5/04
Filed: 1929-03-16
Abstract: 330,029. Vickers-Armstrongs, Ltd., and Pratt, H. B. March 16, 1929. Mines, marine. - The hydros t a t i c depth-setting devices of mines, carried in open chambers on a submarine, are controlled by compressed air from the interior of the vessel. A mine C, Fig. 1, is held in position in the chamber B of a submarine A by a stopmember D mounted on a rotatable shaft. The mine has a hydrostatic depth-setting device E, Fig. 4, which is connected to an isolating valve F by tubing E<1>. Compressed air is supplied to the valve F from the interior of the vessel through a tube F<4>, a stop-valve F<6>, a connection F<2> and an armoured pipe F<2>. When laying a mine, the valve F<6> is closed when the required pressure in the device E has been reached and the stop D is moved, thus releasing the mine which commences to fall. In falling, a handle F<1> of the isolating-valve F is rotated by a stop B<1> and the valve is then closed by its spring F<9>. On further downward movement of the mine, the pipe F<2> is disconnected from the valve F. The hydrostatic depth-setting device is similar to that described in Specification 264,973, and comprises a drum E<2>, carrying a wire E<3> connected to the anchor. The compressed air acts against a hydrostatic diaphragm E<6> which transmits the pressure to a spring- operated lever E<4x>. A stop E<4> on the lever cooperates with a stop E<5> on the drum E<2>, when the mine is at its required depth, and prevents further rotation thereof. A preliminary mechanical setting of the depth-setting device, in acrordance with the low-tide level at the spot whore the mine is to be laid, is effected by displacing the fulcrum E<9> of the lever E<4x>. The compressed air setting is then applied to correct for the height of the tide at the time of laying

Abstract: 1,237,206. Steam driven winches. YUTANI JUKO K.K. 18 Feb., 1969 [28 Feb., 1968], No. 8798/69. Heading B8B. [Also in Division F1] An apparatus for controlling tension in a mooring rope comprises a rope drum mounted for rotation with the crank-shaft A of a double acting two cylinder steam engine B, the variation in winding torque produced by the cranks I of the engine during each cycle being reduced by a relief valve 3, periodically adjusted by a cam 1 rotatable with the crank-shaft A, to vary the steam pressure acting on the appropriate engine piston H. The cam 1 is set relative to the crank-pins such that as the point of maximum crank torque is approached the flats on the cam contact a follower 7 which through linkage 6, 10, 5 releases the pressure on a spring 4 whereupon . the valve 3 is progressively opened by steam pressure from an engine outlet B. Each opposed pair of corners on the cam 1 are associated with the control of one of the engine cylinders. The engine torque variations are similarly adjusted whether the engine is winding in slack rope or being reversed by excess tension in the rope. The value at which the relief valve 3 is opened, which is related to the desired tension in the rope, is set by a handle. 11 which adjusts the initial pressure of the spring 4 and is indicated on a scale 13. The steam engine may be manually controlled by a lever E controlling a steam passage changeover valve D once the relief valve 3 has been locked in the closed position, a small capacity steam input cock 15 has been closed, and a high capacity steam input cock has been opened.
